Hello Nick,

I worked on a renderfarm management software in the past, and what I
would do is read the stdout of the external process (in that case, a
command-line renderer like Mental Ray or Maya/Lightwave's command-line
renderers, in your case osgdem) and parse it. On a Unix variant, you
can just open a pipe to the running process's stdout (IIRC), but on
Windows I don't know how you'd do that.
Once that's done, you'd have to find tokens that allow you to deduce
the progress and use that to give feedback. I can't really help you
for that, as I don't know what kind of output osgdem produces...
So I guess I didn't really add to what you already knew, other than to
say it can be done. :-)
Good luck,
J-S
